D. 19.2%
Answer:
The monthly percentage rate would be 1.6%
Step-by-step explanation:
Given,
Finance charge = $ 85.50,
Amount of bill in this month = $ 5,343.75,
Hence, the monthly rate of percentage
[tex]=\frac{\text{Finance charge}}{\text{Amount of bill}}\times 100[/tex]
[tex]=\frac{85.5}{5343.75}\times 100[/tex]
[tex]=\frac{8550}{5343.75}[/tex]

The range of which function is (2, infinity)? y = 2x y = 2(5x) y = 5x +2 y = 5x + 2
Answer:
I think your functions are [tex]y=2^{x}[/tex] ,[tex]y=2*5^{x}[/tex] and [tex]y=2+5^{x}[/tex]
If yes then then the third function which is [tex]y=2+5^{x}[/tex].
Step-by-step explanation:
The function [tex]c^{x}[/tex] where c is a constant has
Domain : [tex]c\geq 0[/tex]
Range : ( 0 , ∞ )
The above range is irrespective of the value of c.
I have attached the graph of each of the function, you can look at it for visualization.
[tex]y=2^{x}[/tex] ⇒ This function is same as [tex]c^{x}[/tex] so its range is ( 0 , ∞ ).[tex]y=2*5^{x}[/tex] ⇒ If we double each value of the function [tex]y=5^{x}[/tex], which has range ( 0 , ∞ ), but still the value of extremes won't change as 0*2=0 and ∞*2=∞. Therefore the range remains as ( 0 , ∞ ).[tex]y=2+5^{x}[/tex] ⇒ If we add 2 to each value of the function [tex]y=5^{x}[/tex], which has range ( 0 , ∞ ), the lower limit will change as 0+2=2 but the upper limit will be same as ∞. Therefore the range will become as ( 2 , ∞ ).Answer:

From 10 names on a ballot, a committee of 4 will be elected to attend a political national convention. How many different committees are possible?
Answer:
Number of committees that are possible =210
Step-by-step explanation:
Total names in ballot = 10
Total members to be elected for the committee = 4
So, we need the number of different ways in which 4 names out of 10 can be elected for the committee.
To find the number of ways in which the committee can be elected, we use the combinations which is given as
[tex]aCb=\frac{a!}{(a-b)!b!}[/tex]
where [tex]a[/tex] represents total number of members and [tex]b[/tex] represents total number of members to be elected.
So, [tex]10C4=\frac{10!}{(10-4)!4!}[/tex]
[tex]10C4=\frac{10!}{6!4!}[/tex]
[tex]10C4=\frac{10\times9\times8\times7\times6\times5\times4\times3\times2\times1}{6\times5\times4\times3\times2\times1\times4\times3\times2\times1}[/tex]
[tex]10C4=\frac{10\times9\times8\times7}{4\times3\times2\times1}[/tex] [Canceling the common numbers]
[tex]10C4=210[/tex]
∴ Number of committees that are possible =210
Using the combinations formula, we will see that 210 different committees are possible.
How many different committees are possible?
Here we need to use the combinations function. It says that for a set of N elements, the number of different subsets of K elements (such that K is equal or smaller than N) that we can make is:
[tex]C(N, K) = \frac{N!}{(N - K)!*K!}[/tex]
In this case, we have N = 10 and K = 4, replacing that we will get:
[tex]N(10, 4) = \frac{10!}{(10 - 4)!*4!} = \frac{10!}{6!*4!} = \frac{10*9*8*7}{4*3*2} = 210[/tex]
This means that from 10 names, there are 210 different committees of 4 members that can be made.

A television and DVD player cost a total of $1192 . The cost of the television is three times the cost of the DVD player. Find the cost of each item.
The cost of the television is $894, and the cost of the DVD player is $298.
Let's denote the cost of the DVD player as x dollars.
Since the cost of the television is three times the cost of the DVD player, we can express the cost of the television as 3x dollars.
According to the given information, the total cost of both items is $1192. Therefore, we can set up the following equation:
[tex]\[ x + 3x = 1192 \]Now, let's solve for \(x\):\[ 4x = 1192 \]\[ x = \frac{1192}{4} \]\[ x = 298 \][/tex]
Now that we have found the cost of the DVD player [tex](\(x = 298\) dollars)[/tex], we can find the cost of the television, which is three times the cost of the DVD player:

Ta Da I have taught you the pattern now you can show your work just in case you have one of those teachers hope this helped
The next number in the pattern 1,7,8,15,23,38,61 is 99. The pattern can be understood by calculating the differences between consecutive numbers, and observing a pattern in these differences.
Explanation:Let's take a look at the pattern 1,7,8,15,23,38,61 closely. At every step, we're adding an increasing number to get to the next term in the sequence. From 1 to 7, we add 6. From 7 to 8, we add 1. From 8 to 15, we add 7, from 15 to 23, we add 8, from 23 to 38, we add 15 and from 38 to 61, we add 23.
The difference between these numbers (6, 1, 7, 8, 15, 23) reads as follows: 5, 6, 1, 7 and 8. So, the next difference could be 15 (continuing the pattern in the differences). So, the next term would be obtained by adding 15 to previous term's difference (23) and then adding that result to 61.
Finally, we calculate 61 + (23 + 15) = 61 + 38 = 99. So, the next number in this pattern should be 99.

Marcelo played a carnival games six times he spent three tokens to play each game and he won seven tokens each time write two different expressions that can be used to find the total profit and tokens that Marcello made
Answer:
24
Step-by-step explanation:
let W represent the number of wins and let P represent the number of plays let T represent profit from each play. from the question, Marcelo played 3 times, this means 3P can represent the first equation He won 7 times, 7W can represent the second equation
Read more at Answer.Ya.Guru – https://answer.ya.guru/questions/5930426-marcelo-played-a-carnival-games-six-times-he-spent-three-tokens.html
Certainly! Marcelo played the carnival games six times, spending three tokens for each game and winning seven tokens from each. To find the total profit in tokens that Marcello made, we can create two different expressions:
1. The first method involves directly calculating the net tokens won over all the games:
- We calculate the total tokens won by multiplying the number of tokens won per game (7) by the number of games played (6).
- Then we calculate the total tokens spent by multiplying the number of tokens spent per game (3) by the number of games played (6).
- Finally, we determine the total profit by subtracting the total tokens spent from the total tokens won.
Using this method, the first expression to calculate the total profit (P_1) is:
\[
P_1 = (\text{Tokens won per game} \times \text{Games played}) - (\text{Tokens spent per game} \times \text{Games played})
\]
\[
P_1 = (7 \times 6) - (3 \times 6)
\]
\[
P_1 = 42 - 18
\]
\[
P_1 = 24
\]
So, using this expression, Marcello's total profit is 24 tokens.
2. The second method is to calculate Marcello’s profit per game and then multiply that by the number of games played:
- First, we find the profit per game by subtracting the number of tokens spent per game (3) from the number of tokens won per game (7).
- Then we multiply the profit per game by the total number of games played (6) to find the total profit.
Using this method, the second expression to calculate the total profit (P_2) is:
\[
P_2 = (\text{Profit per game}) \times \text{Games played}
\]
\[
P_2 = (\text{Tokens won per game} - \text{Tokens spent per game}) \times \text{Games played}
\]
\[
P_2 = (7 - 3) \times 6
\]
\[
P_2 = 4 \times 6
\]
\[
P_2 = 24
\]
So, using the second expression, Marcello's total profit is also 24 tokens.
In both scenarios, the profit that Marcello makes from playing the six games is 24 tokens. The first expression gives us a direct calculation of the total, while the second expression calculates the profit on a per-game basis and then accumulates it.

Marsha serves the Volleyball to Rhonda with an upward velocity of 14.5 ft./s. The bar is 4 feet above the ground when she strikes it. How long does Rhonda have to react, before the Volleyball hits the ground? Round your answer to two decimal places.
Answer:
The taken by Rhonda to react before volleyball hits ground is 2.39 seconds
Step-by-step explanation:
Given as :
The upward velocity of the volleyball = 14.5 ft/s
The height of the ball above ground = 4 feet
Consider value of acceleration due to gravity = 9.8 m/s
Let the time for Rhonda to react before ball hits ground = t sec
Now,
S = u t + [tex]\frac{1}{2}[/tex] a t²
where s = height
u = initial velocity , a = acceleration due to gravity , t = time in sec
So, 4 = 14.5× t + [tex]\frac{1}{2}[/tex] × 9.8 × t²
or, 4 = 14.5 t + 4.9 t²
or, 4.9 t² + 14 .5 t - 4 = 0
Now, solve for t
t = [tex]\frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}[/tex]
or, t = [tex]\frac{-14.5\pm \sqrt{14.5^{2}-4\times 4.9\times (4)}}{2\times 4.9}[/tex]
Or, t = [tex]\frac{-14.5\pm \sqrt{80.5025}}{9.8}[/tex]
Or, t = - 2.39 , - 2.76
Hence The taken by Rhonda to react before volleyball hits ground is 2.39 seconds . Answer
